Public ISBD [article]  in Materials and corrosion > Vol. 62 N° 1 (Janvier 2011) . - pp. 47–52 Titre : Corrosion inhibition of copper in tetra-n-butylammonium bromide aqueous solution by benzotriazole Type de document : texte imprimé Auteurs : S. Liu, Auteur ; J. M. Duan, Auteur ; R. Y. Jiang, Auteur Année de publication : 2011 Article en page(s) : pp. 47–52 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Benzotriazole  Copper  Inhibition  Tetra-n-butylammonium  bromide Index. décimale : 620.1 Essais des matériaux. Défauts des matériaux. Protection des matériaux Résumé : The corrosion inhibition behavior of benzotriazole (BTA) on copper in 17 wt% tetra-n-butylammonium bromide (TBAB) aerated aqueous solution was investigated by weight-loss tests, potentiodynamic polarization, electrochemical impedance spectroscopy, and scanning electron microscopy/energy dispersive X-ray spectroscopy. BTA is a good inhibitor in 17 wt% TBAB solution. The inhibition efficiency of BTA increases with increasing inhibitor concentration, attaining efficiencies of up to 90% calculated according to different methodologies. Adsorption of BTA in 17 wt% TBAB solution on the copper surface was found to obey the Langmuir adsorption isotherm.

A stochastic dynamic programming model for valuing exclusivity from encroachment in franchising / S. Tikoo in Journal of the operational research society (JORS), Vol. 63 N° 2 (Fevrier 2012) 

Public ISBD [article]  in Journal of the operational research society (JORS) > Vol. 63 N° 2 (Fevrier 2012) . - pp. 151–159 Titre : A stochastic dynamic programming model for valuing exclusivity from encroachment in franchising Type de document : texte imprimé Auteurs : S. Tikoo, Auteur ; S. Liu, Auteur ; S. K. Nair, Auteur Année de publication : 2012 Article en page(s) : pp. 151–159 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Franchising  Territorial  encroachment  Exclusivity  Stochastic  dynamic  programming Index. décimale : 001.424 Résumé : Valuing territorial exclusivity in franchising is difficult because of the uncertainty associated with variables such as future franchise sales and brand strength. We present a stochastic dynamic programming model to value the exclusivity option from the perspective of both the franchisor and the franchisee. When there is positive value to the franchisor of including the exclusivity option in the contract, and to the franchisee of purchasing this option, the likelihood of franchisor-franchisee encroachment-related conflict is reduced. We also discuss structural results and explain our results using a numerical example.

The synergistic effect of Na3PO4 and benzotriazole on the inhibition of copper corrosion in tetra-n-butylammonium bromide aerated aqueous solution / S. Liu in Materials and corrosion, Vol. 63 N° 11 (Novembre 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 11 (Novembre 2012) . - pp. 1017–1025 Titre : The synergistic effect of Na3PO4 and benzotriazole on the inhibition of copper corrosion in tetra-n-butylammonium bromide aerated aqueous solution Type de document : texte imprimé Auteurs : S. Liu, Auteur ; Dong, J., Auteur ; W. W. Guan, Auteur Année de publication : 2014 Article en page(s) : pp. 1017–1025 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Benzotriazole;  copper;  inhibition;  sodium  phosphate;  tetra-n-butylammonium  bromide Résumé : The effect of Na3PO4 and the mixture of benzotriazole (BTA) and Na3PO4 (SP) on the corrosion of copper in 17 wt% (0.534 mol/L) tetra-n-butylammonium bromide (TBAB) aerated aqueous solution has been investigated by means of weight-loss test, potentiodynamic polarization test, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy/energy dispersive X-ray techniques. The experimental results showed that a dosage of Na3PO4 stimulated the copper corrosion, and the corrosion rate increased with increasing Na3PO4 concentration, whereas the mixture of BTA and Na3PO4 could protect copper in aqueous TBAB solution. The inhibition action of the mixture of BTA and Na3PO4 on the corrosion of copper is mainly due to the inhibition of the anodic process of corrosion. The inhibition efficiency of a mixture consisting of 2 g/L BTA and 1 g/L Na3PO4 was about 96%. The mixture of BTA and Na3PO4 inhibits the corrosion of copper better than BTA by itself, indicating that Na3PO4 has a synergistic role with BTA on the corrosion inhibition of copper in TBAB aqueous solution.
